svn revision in uname

[Ian Smith]

Hi all,

I've been using svnup for source updates for ages, and for my occasional 
use it works fine.  However one thing you don't get is the svn revision 
shown in uname, eg % uname -vm
 FreeBSD 9.3-STABLE #0: Thu Oct 29 03:18:26 EST 2015 
 root at x200.smithi.id.au:/usr/obj/usr/src/sys/GENERIC amd64

I know where to find it:
smithi at x200:~ % ll -rt /var/tmp/svnup/
total 30400
-rw-r--r--  1 root  wheel  3736967 Apr 22  2014 stable.apr
-rw-r--r--  1 root  wheel  3738448 Jun 25  2014 stable.jun
-rw-r--r--  1 root  wheel  3738347 Jul  6  2014 release
-rw-r--r--  1 root  wheel  7926790 Jan 23  2015 ports.first
-rw-r--r--  1 root  wheel  7927003 Jan 23  2015 ports
-rw-r--r--  1 root  wheel  3750256 Oct 10 16:43 stable

smithi at x200:~ % head -1 /var/tmp/svnup/stable
289106

but I don't know where to poke it so build|install world|kernel find it?

One of the reasons I prefer svnup on this very (64GB) space-constrained 
laptop is that it doesn't need svn's extra copy of the repository, but 
I'm happy to add a /usr/src/.svn dir with whatever is needed for this.

Hoping the answer is not "the build needs svn installed to get that" :)

cheers, Ian  (please cc me, subscribed to the digest)
